Question

I am having a problem “500 Internal Server Error” when I used web service call. What is causing this problem? How to resolve it?

Please advise me..

Here’s my code:

   MailMessage objEmail = new MailMessage(new MailAddress(ConfigurationManager.AppSettings["emailAdd"].ToString()), new MailAddress(ConfigurationManager.AppSettings["emailAdd"].ToString()));
    objEmail.Subject = "Test";
    objEmail.Body = "EJSCODE:" + _Message;
    objEmail.Priority = MailPriority.High;
    SmtpClient SmtpMail = new SmtpClient();
    SmtpMail.Host = "localhost";
    SmtpMail.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
    SmtpMail.PickupDirectoryLocation = @"C:\Inetpub\wwwroot\MailMsg2"; 
    SmtpMail.Send(objEmail);

Also you can look at IIS log, that by default stores at C:\Windows\System32\LogFiles\W3SVC1
– there you can find the error description
